PATIENT SAFETY AND OTHER PRECAUTIONS
Radiation protection for intraoral radiography
WARNING
During the exposure, nobody but the patient should be inside the useful X-ray beam. The operator must
be at least 6 feet away from the X-ray head, and not in the direction of the radiation.
Full use of the length of the handswitch exposure cable should be made.
For
dental
radiography,
the
patient
should
hold
the
film
himself
with
the
hand
or
a film
clip
should
be
used.
If
this
is
not
possible
(with
children
or
severely
sick
persons),
the
film
should
be
held
by
a
relative
of
the
patient
but
not by the dentist
or
his
assistent.
We
recommend,
the
use
of
lead
apron
(0,25
mm
lead),
in
order
to
obtain
maximum
protection
of
the
pa-
tient's
reproductive
organs
against
scatter
radiation.
WARNING
Since the Portable X-ray unit requires assembly-disassembly as same is transported from
location to location, you the USER are required to perform a power supply line adequacy
test as outlined in these instructions every time the unit is re-assembled for use and docu-
ment same on the TEST RECORD as provided, last pages of the operating instructions.
WARNING
Visual checks must be performed before connecting the unit to an adequate power supply.
WARNING
When the unit is set-up in preparation for Radiography you as the installer/assembler must verify the
following:
ir Verify that all labels are affixed and legible. Look for mechanical damage, possibly affecting radia-
tion safety, (inspect collimator for possible cracks, test the tubehead in all working positions for
possible drift). |

The operating-ready light (green) must light up and the meter must be functional.
WARNING
Mechanical damage affecting radiation safety be evident, the user is not permitted to use the unit until re-
pairs or replacements, correcting the defect(s), are made.
Defective bulbs for power “on” light, ready light, radiation light constitute a safety hazard to the patient as
well as to the operator, therefore, repairs or replacements must be made promptly, same rule as above
applies.
During line adequacy tests:
WARNING
Observe radiation protection as outlined above
k Check radiation warning light and acoustic buzzer for proper functioning.
2. Make sure the X-ray exposure is interrupted after releasing the exposure switch (dead man feature).
